.To all whom it may-concern:

Be it knownthatI, J 91m PFEIFER, a citizen of the United States, residing Springfield;

in the. county of Clark and State of Ohio,

'heve invented certain new and useful'improvements in Wrapping-Machines, of which the following is a sfecifioation;

My invention re a e-wrap'ping' machines, and e'specia y to package-cover is secured by twistin the ends.

. .The device hereinafter dcscrih is espe-' ciallv edafi'ted for wrapping small pieces of candy one *in' a separate paper wrapper and securing the same bytwistmg the on s. Howi ever, by modifying the pro ortions of the various parts the mechanism herein shown may be adapted to operate on various articles of 'various sizes, including different kinds 'of he object. (if-my invention is to greatly simplify the construction. as well as the ."-means and modes ofoperation, of such ma chincs, who-relay they are not only cheepened, but ere rendered unlikely toget out of order and are'made easy ofoperationl With the above primary and otherincidental objects inview the invention consists (of mode of-opcration hereinafter described, and

As shown in Fig. ,5, vt-heierni a ispreferably mo formed fist; wens 'rectsngulsr'notch a in its lower edge, and the trigger a is provided with a shoulder near its inner end to engage in said rectangular notch. There is also pitfoted to the heads a bell-crank lover a, one end of which normally contacts with the oxtre'mit of the arm a and the other extends laterally into the path of an ad ustable stop es s'aid' trigger from the arm a" andf theepa er' web,

a", mounted on, the bar a. The head a is caused to slide forward and back on thebar a by means of a link a and a pivoted arm a", which is sprin -actuated in one direction by a s a". he movement of the arm a", an thereby the head a is re lated by a face-cam a','carried on the en of the main shaft 1, Figs. land 2.

R eferrin to Fi 1, as the cam a rotates, as indicated by t e arrows, under the influence of ower applied to the driving-wheel 2 atthe o 'posite end of the shaft 1 the pivoted arm" 0 ca 'ng with it the head a, will move inward y as the roller a travels over the inclined portion-a of the cam a. At the time the roller a" drops off the extremity ofthe inclined cam portion a" the head a hasnpproaiched the end of the paper web.

the'said roller drops from the incline the headis-suddenly advanced. The trigger c contacts with an adjustable stop a, which allows t e' jaws a, a to close upon the end of which they do b extending 111150 arectangular notch a" in the plates a and a". 'The objectof the sudden drop off at the 'extremity 'of the inclined cam portion a is to give to the head a sufficient momen-- tum to tri the-trigger a"; This might also beacoomp ished" by increasing the tension of the'spring'a", but would require additional power-to overcome this spring in returning :the parts to normal position? Therefore the first method is preferable. The pulling-jaws ha thus engaged the end of the paper web; t e cam a in-its continued movement will cause the head a to travel back as the roller a travels ove'r'the inclined portion a until it reaches the dead portion a", when the head a' will for a moment remain at rest, 'wi'th'theouter end ofthe bell-crank lever a in'contact with the sto 1a". Durin backward movement of t e head a su cient paper will have been peril-led from the web to 01m one wrapper.

Maine at rest, as before mentioned, the

- length of paper is'severed from the web by a mittedqby t arrangement the stroke of the paper-knife b,

, knife bis formed with twocutting ed es Figs.2 Pa ercutting m'eckanismw l he knife is pivoted on'a longitudinal sha t .3. o a-downwardlyrojecting arm b there is attached a spring 1:, adapted to throw the khife forcibl against the pa er when so pere cam b, over he peri hery of which the roller b travels. The blade of the b b", arranged 'angularly to each other. y this paper is severed by bein 3, 4, and e.

- punctured near the center by the apex' b an then cut in both directions to its edges. The friction-plate a forms a support for the paper while being cut, and'in order that the paper may be properly supported at the rectangula notch where it would otherwise tear there is provided'a'supplementary'piuoted support the le the head a reb, hinged on the bar A the position shown in Fig. 4 by the spring '1), the movement inone direction being limited by the contact of the stop-arm b with the bar A The support I) is further supplied with a lateral arm 1)", adapted to be contacted by the vhead a, whereby the said su will be moved from the path of the pu lingjaws a a, at the proper time. After the paper has thus been severed the raised portion a. of the cam a in its movement will release the pulling-jawsfrom the paper by giving to the cad a an additional movement, whereby the outer extremity of the bell-crank lever a will contact with the stop a" and be turned about its pivotal point,.and the inner end of pressing on the lever a," will open said lever the pullingj aws until the lever a" by the tr gger a". en thus disen aged 'from the ceding devices, the pa er will be held between" a pressurearmcan a tympanplate 0 Figs. 1, 2, and 3, pivotally attached to the a spring c, which tends to throw the tym anplate 0 into proximity with the ath 0 the paper while eing ulled fromtlib web, the movement in this irection being limited' by the contact of the arm 0 with a stop 0 on the inner side of the bar A. The pressure-arm c is pivoted on the shaft 3 and is actuated by a spring c, the movement being regulated by a cam c on the operating-shaft I. Said ressure-arm c, is provided with a ivoted ead c of a length substantiall equa' to the width of thetympan-plate c. he object of pivotally connecting'thehead c is to make the same self-adujstable, so that the pressure at both ends may be equal. As the ressurearm 0 m'oves inwardly under the in uence of the spri c and cam c it carries the severed portion ol the. paper with it, forcing thetympan-plate about its .pivotal points until it contacts with the wrapping and twisting mechanism, and the paper is now'in position to'be operated u on. I

- Wrappinga twisting mechanism. -There are two sets of wrappi and twisting mechanism extendin inwar 1y from the upright frame A and a ove theshaft 1, andias the two sets are identical in construction 'and o eration only one will be described, which escription will apply e uallysto the other. It must be understood, owever, that the relations of the parts are reversed, the sets of mechanism being arranged right and left handed. m

Referring and normally held in ort is engaged longitudinal rod A and provided with to Sheet 4 of the drawings and paricularly to Fig. 7, the wrapping and twistmgl mechanism is mounted on a splined shaft e, aving a bearing in the upright frame A and a second" bearin outside said frame A,' preferably in a racket e, extending therefrom; but this second 'bearin might be in' an entirely. separate upright ame. At the inner end the shaft e carries a cylindrical Attached to the disk head 6*, preferabiy having a rubber covering e. in proximity to this head a there is rigidly secured to the shaft e a disk 8, havin r on the side toward said head a projecting hub e. Slidingly mopnted on the shaft e, but adapted to rotate therewith by means of engagements with the spline of said shaft, are twodisirs e and e. To provide better hearing, these disks are equipped with sleeves e' and e. v

, e and extending through openings in the disks eand'ef are two small rods e", having L-shaped grippingat their extremities having )ivotal connections with said rods e", locate in the angle of said L-shaped fingers. Attached to the disk e and extending through the disk e is a rod e", having a finger e in all respects like those. before mentioned. -Attached to each of the rods s and e", respectively, and to the disk efare springs e, which tend to pull said rods, with their connections, inward] toward the heads c. .When thus mover inturned on their 1 the periphe wardly, the short arms of the L-shapod Ippingmembers contact with the face 0 the cad e, and the said gripping-imgers are ivotal connections until the longer arm of said fingers is pressed tightly on of said head 2 as is shown the finger e of i s. 2-and 7. .the' fingers to chose under theinfiuence of the springs e is resisted until the proper. moment by the lovers e and, e", pivotally secured to the her At For convenience of adjustment said lovers are secured through aslotted opening e". in said bar A. These levers e a are controlled by cams d'd' onthe shaft 1 and are "provided at t \eir lower ends with rollers 12 ands, whio travel over the face of said dams. At the upper end the lever c has a roller e engaging the inner face of the disk iariy-constructed gears, as illustrate e, and the lever e is provided with a bifurcated stud e, straddlin the edge of the disk 'e, thereby causing the isk e to be moved in either direction by the IHOVelllBDt of the iever a. The tendency of this disks to move inwardly or in opposition to the cam d is increased bya spring a", attached at oneend to the lever e and at the other to the bar A Fig.1.

An intermittent movement is transmitted to the shaft 6 from the main shaft 1 b cul- 9. The larger gear j on the main operatingshaft is a mangled face-gear ha a projecting face f, the radius of whic corresponds tothe radius ofthe sides f of'the small gear f, which is splined on the shaft e.

The contact of the convex projectin face f of the lar e gear with the concave ace 3 of the smal gear prevents the letter from turnin except whenmovedby the pins or teeth of t c f'aceear. In this respect the .construction of 1; ese gears. is

periphery of the quite similar to what is technically known as 'their attached re s tatesas indicated by The tendency of The lower clamping member 1'. is. I only a vertical movement and is actuated by the Geneva-stop movement of watch and clock construction.

When the section of paper g, F ig. 2, destined to form the wrapper, is pressed against the heads e by the prcssurc arm c, the relative position of the gears and f 3 is as shown in Fig. 9 and that of tie gripping-fingers each extended, as in Fig. 10. At. this mo- 'ment the rollers e and e" of the lovers e and e have reached the summit of the inclines d and d of the cams d and d, respec: tiveiy, thus forci :the disks e" and e, with and'gripping-fingers, to their extreme outward position, in which the. short arms of the grip in -fingers e and e" contact the hub a of the isk e, and messgels are turned on. their-pivotal points to their extreme open position, Fig. 10. In the continued rotation of the camsd and d with p of the lever 6 drops over the slg oulder d of. the cam d, which ailowsthe disk e to move inwardly under the influence of the spring eEhand the finger closes on the lower portion of t e pa erg, as shown The shaft l wit the gear f,'ro-

V the arrow, and the group j. of two teeth or pins on the face gear f engages the gear-j" and ives to itand the connected mechanism a, elf-revolution, which brings the paper and fingers to the position shown in Big. 10", where they again come to rest. 7 Thepapcr. being in the form of 'a semi-' circular 'trong is in. position to receive the candy, which is deposited as-hercinafter de scribed. (See Fi .13.)

After the deposit of the candy the group j' of teeth of the gear engage the gear f and give to it and the mapping mechanism a in Fig. 10..

complete rotation; which carri s the parts to the position indicated in F 10?, the paper being in-a straighttubular orm Fig. 14, with the candy inclosed. At this time the roller e of the lever 0 passes over the ofl'set d of the cam d, which perinits'the disk e, with its attached rods and fir ers, to move inwardly under the influence 0 their respitetivesprzngs e, and the fingers e" are caused to gi'ip the paper; as shown in Fig; 10. The pac is now ready for the twisting of the 2]. *8 ends; but as both sets-of the wrapp and twisting mechanism rotate in the same irection it is necessary to hold the candy within" the acka stationar during theo oration. Ilding mechanism'1he\holdid g n'iechanism is indicated in Figs. 1 and 3 and indetail in F 11 and 12. The lower clam in member t is provided with aninciined dead a",- having a depression therein of slightl eater radius than the article to be wrappe here is also rovided a slot}? in themember: i, engaging tliqshaft 1-, and an extended leg i h'avmg a guide t, located on. the basalt.

capableof a earn 1'. on the shaft l'engaging with a roller i on said member I. T-heupper clamping member has a com ound movement, its line of travel bein simi ar to the outline of a. arallelogram. t consists of a shaft h, .ent into a U form, Fi s. 1 and 11, one leg having a bearing onaplite h, attached to the bar A. At its upper portion this plate is extended horizontally rearward, forming a table h, upturned at the end, which is slotted to permit the passage of the head i of the as in dot-and-dash lines of'Fig.

lower clamping member i. A spring h", coiled about the lower le of the U-shaft h, tends to throw said U-sha t forward or away from the bar A, which movement is resisted by the action of a cam 72., mounted on the Shaft 1 and acting on a rearwardly-extendarm h, attached to the lower leg of said U-sha ed shaft. Pivotall connected to the upper eg of said U-sha. ed shaft h is a plate havin an extende .arm terminating in an arche portion h, of somewhat greater radius than the average articleto be wra ped. A spring h tends to move this plate h ownwardly about its-pivotal connection, which movement iso posed by the cam h and link It". The link "is pivotally connected with the plate h. Its op osite end is bifurcated- A roller h on the 0 lines in Fig. 12. At this time the roller h" of the link It" travels onto a hi her portion of the cam h, and the pivoted p ate h is forced upwardly against the tension of the spring h, 12. As the arm it travels toward ;the hig r portion of the cam h the U-shaft It moves rearwardly or toward the bar A until the plate h assumes the position shown in broken lines in Fig. 12.

During this rearward movement the candy 5o or other article to be wrapped is de osited in the paper, as will hereinafterbe ascribed. At this time the wrapping mechanism is given the complete rotation before menthe tioned formin the pa er as in Fig. 14. The roller '1. of the ower cl iimping memebri has traveled during this rotary movement from thelower to the higher portion of the cami' and the head 'i of the membensi has been brought into contact with the under side pf acka e. The roller h" of the link 722 sud. enl (ire s over the point h" of the cam It, and {he p ate h-moves downwardly with the arched ortion h over the'packa e,which is securely eld between said arche portion h and the head 1'. ofithe member i,--as-shbwn in full lines in Fi 12.

The group f o six'teeth .on the gear f now engages the g'earf and gives tothe Wraping mechanism a. revolution and a half, whic results in the twisting of theends. 'ofthepacka age, since the center of the package is heldstationary by the clamping devices .beforethe ,cams d and d, which they do simultane ously, the wrapping and twisting mechanism is returned to normal position-. The. short arms of the fingers e and e" contactmg with the hub e, the' grip 'ing-fingers release the ends of the package, t e lowerclamping member drops away from the package, thev U-- shaped shaft h at the same time turns about its pivoted connection to theyextreme outward osition under influence of the spri h and the wrapped package is ejected from the machine.

It is obvious that the wrapping mechanism can be so modified as to employ various amounts of paper, as by adding two teeth-to the roupf the wra per instead of being extend ed once and a lialf around the article would be extended twice around, giving a double thickness. In a similar manner the number of twists given to the'ends of the package may be modified, as by adding two teeth to the group j. instead of a twist and a half two complete twists can b 'ven -to each end. It is to be noted that bot ends-ofthe package are twisted in the same direction, Fig. 15 showing the completed package with both ends twisted away from the 0 server.

It is further to be noted that the forming, wrap ing, and twisting operations are all accomplished b the same set of mechanism.

Articlefee i1 meclwnism.1n Figs. 1, 3, and 12 there is s own for the reception of the articles to be wrapped a chute or hopper j terminating substantially over .the semicircular paper-trough formed preparatory to the depositing olithe, article therein. The lower IIO end of this hop er'j is slotted'at 7'' (see Fig.

1) and provide with a s ring-actuated gate Formed on the top oi the arched portion it of the plate It is an upwardly-extendi the outward or forwar finger 7'. During movement (if the U-shaft h the plate h? is in i its depressed position, as shown in dotted lines in Fig. 12, and the fin er 1" passes under the hopper 7'. However, w en at the limit of the movement of the U-shaft h the plate It is closes the'hop er 1' a einst t forced upwardly bycction of the link h" and cam h, the finger j enters the slot 1' behind the'lowermost article in the hop )er 7', as shown by dot-and-dash lines in lg. 12.

During the forward movement of the 'U- frame the finger f pushes thelowest article from the hopper against the resistance of the gate 7", which immediately springs hack and 1e escape-cf the next lowest rticle, t article ejected from the hopper meanwhile having dropped into the semicircular pa er-trough previously prepared, es hereinbe ore mentioned.

The mechanism thus for described may he used for wrapping various articles, fruit, and ieces of can y which have previceslyl heen ormed and cut to the ro'per' shape and length. In addition to tlns there is shown in v 1 and 3 mechanism for operating upon candy in a mass by rolling it to proper shape,
